Description

420736 V. Description of the invention (1) The present invention relates to a method and a device for reinforcing a long-fiber non-woven fabric by using long fibers as a reinforcing material for the non-woven fabric, and through a screen-laying device and a longitudinal wire feeding device capable of continuously changing the fiber-laying angle. It can be used with different nonwoven production line speeds, a novel manufacturing method to reinforce, advance longitudinal, transverse and oblique directions of non-woven fabrics, has better dimensional stability and uniformity, and better MD / CD tensile strength ratio ( Close to 1), especially suitable for stiffened non-woven products, such as geotextiles, artificial leather base cloths, dust filter cloths, etc. The structure of short-fiber needle-rolled nonwovens is based on the entanglement and friction between fibers and fibers, so the tensile strength and tear strength of nonwovens are low, while the tensile strength is higher, making nonwovens prone to deformation and tear. Therefore, in order to improve the mechanical properties of short-fiber nonwovens, the long-fiber reinforcement method is mainly used. The manufacturing method of conventional long-fiber reinforced non-woven fabric includes the following methods: Republic of China Patent No. 232324 discloses a sandwich non-woven fabric (as shown in Fig. 1). It is mainly composed of a mesh fabric 101 and a non-woven fabric 102, which are arranged in two layers. A non-woven fabric is added with a scrim, and then consolidated by a needle to form a sandwich structure. At present, the dust collection cloths with high size stability are all of this structure. Japanese Patent Publication No. 52-20567 'Reveal-Reinforcement method of non-woven cloth and paper' is used between two layers of non-woven cloth or paper, and a scrim made of polypropylene fibers is used to consolidate into sandwiches by hot-pressing wheels. structure. Republic of China Patent No. 131 01 6 discloses a reinforced non-woven fabric, which is composed of a composite carded web containing at least 15% of composite staple fiber and a composite staple fiber containing at least 5%

Description of the invention (2) Dimensional reinforcing cloth (scrim) is laminated by heat pressing to form a composite non-woven cloth. Japanese Patent Publication No. 56-5879 also discloses a method for reinforcing non-woven fabrics and paper. It is used between two layers of non-woven fabrics or papers, using a scrim made of polyamide and polypropylene fibers. The rollers are consolidated into a sandwich structure. The mesh (s c r i m) used in the aforementioned patent reinforcement must be prepared, reinforced, and knitted after preparation, weaving, and other preparation and weaving works. Therefore, the manufacturing process is complicated, time-consuming, and costly. U.S. Patent No. 53 9 668 9 discloses a manufacturing method for continuous reinforcement between two layers of non-woven fabrics using continuous yarns or filaments. As shown in FIG. Netting mechanism 2 02, weaving into a transverse reinforcing net 2 03, and a non-woven fabric 205 and a non-woven fabric 206 passing through the non-woven guide roller 2 04 are laminated into a sandwich structure, and then consolidated by water rolling or needle rolling 2 〇7 , Entangled and consolidated into a reinforced nonwoven 208 ′ and then taken up by the cloth take-up shaft 209. The process of this patent only has a transverse reinforcement effect on the non-woven fabric, and has no longitudinal and oblique reinforcement effect, so it is not suitable for non-woven fabrics that require a large longitudinal diagonal tensile strength. Republic of China Patent No. 240029 'Reveals a manufacturing device for multilayer composite nonwovens' as shown in Figure 3', especially the fiber conveying device, which is composed of at least two metal rollers 302 and 303, a rubber roller 304 and two grooves. It consists of wheels 3 0 5 and long fibers 3 6 are arranged at a certain interval in the horizontal direction. They are spread on the first layer of non-woven fabric 307 by a fiber conveying device, and then covered with the second layer of non-woven fabric 3 8 8 and passed through the pin mill. 309 entangled and consolidated into a sandwich nonwoven structure. The long fiber of this patented process is along the transverse direction (width direction) of the non-woven fabric.

420736 V. Description of the invention (3) Arranged at a certain distance, each long fiber will be continuously spread into a web along the non-woven position. Due to the relative f control of two adjacent long fiber webs, the transverse direction of the reinforcing fiber web is uniform. The property will be not worse than 2 ::, which indirectly affects the uniformity and reinforcing effect of the non-woven fabric. Bai Jun's sentence is ROC Patent No. 131016, which discloses a method for manufacturing a reinforced nonwoven fabric using rhombus as a reinforcing material, such as: No. Includes a reinforcing fabric supply unit 401 and a fiber web supply unit 402. Tingqiang nonwoven fabric forming Department 404. Reinforced long fibers 40 5 containing 15% by weight or more of heat-adhesive compound are unwound from the majority of bobbins 407 in the canister 406, and are collected through the sheet f control unit 40 8 and the insertion guide 409. The hot roll 41〇ΐ = interval ② x m is heated and pressed to form a diamond-shaped flower reinforcing cloth 4Π, and then with 15% by weight or more of thermal adhesion: comb = 412, made by the reinforced non-woven forming part Sandwich reinforcement. The non-woven fabric and patented process only have a diagonal reinforcement effect on the non-woven fabric, and the longitudinal and horizontal ° strong performance is poor. For some products that require higher vertical and horizontal tensile strength, such as dust filter cloth and other products are not suitable, Therefore, applications are subject to this limitation. 4 Second Republic of China Patent No. 207257, which reveals-a kind of non-woven fabric structure improvement as shown in Figure 5A) is based on a long fiber layer 501 and a short fiber cotton mesh = 502 composite as a basic composition 503, and consists of Multi-layer basic composition is layered and layered, and then entangled and consolidated by needle rolling mill 504 to grow staple fiber composite nonwoven fabric (not shown in Figure 5B). The long-fiber layer and short-fiber layer of this patented process are first compounded f, after a basic knitting, it is continuously and diagonally stacked on the cotton mesh conveying ▼ through a cotton laminator, and then consolidated into a staple fiber composite nonwoven fabric. Cotton net in

Description of the invention (4) Before consolidation, 'is a fragile strained by long fibers and deformed due to the direction of long fiber arrangement and the fiber arrangement of short fiber carded cotton', and the stacking angle is less than 10 degrees The tensile strength of the cloth is the tensile strength of the parallel card, and outside the vertical card, this process can only reinforce the nonwoven fabric in the horizontal and vertical directions. The present invention is directed to the conventional technique, which can continuously change the fiber laying arrangement 'and can be used with different nonwoven fabric directions, transverse directions and oblique directions to supplement dimensional stability, uniformity, and force ratio. The fiber gathers the mesh layer, so the damage of the cotton mesh will affect the uniformity of the non-woven fabric. The direction of the short fiber arrangement is almost the same as the direction of the card output. Therefore, the stacked cotton will not be output after consolidation. The non-woven fabric has a relatively small reinforcing effect in the direction of output. These can't be reinforced obliquely, which can not improve the above-mentioned shortcomings of the non-woven fabric art, and provide a new type of manufacturing method for the vertical reinforcement of the non-woven fabric, which provides an angled web laying device and a vertical wire feeding production line speed Longitudinal (MD / CD) tensile strength The object of the present invention is to provide a long-fiber reinforcing device, which is a long fiber that achieves the purpose of laterally or diagonally or laterally diagonally or spirally reinforcing a nonwoven fabric by continuously changing the 7-net angle.
